I understand that the function of tuners switching themselves off when not in use is to save power- But its driving me nuts. Often when I have no tuners showing lock and try to access a channel I get a "cannot display this channel" message from the IPTV app in Android. The only way to wake up the box is to use my laptop and vlc player but sometimes this is hit and miss as well.
There should be an option to specify the number of tuners that are always on. Also maybe a setting that when one tuner is in use then another tuner is switched on automatically.
I think the problem is due to the Vbox not reacting quick enough to the command to watch a channel.
